Laptop BIOS Beep Codes – Complete Guide for All Brands (2026)
Introduction
all types of laptops bios beep codes 2026
When a laptop fails to boot and shows no display, the system BIOS (Basic Input/Output System) communicates hardware problems using beep codes. These beep sounds are generated during the Power-On Self-Test (POST) process.
Understanding BIOS beep codes helps diagnose:
- RAM failure
- Motherboard issues
- CPU problems
- Graphics card errors
- BIOS corruption
This guide explains all major laptop BIOS beep codes, including AMI, Award, Phoenix, and brand-specific codes like Dell, HP, Lenovo, ASUS, Acer, Toshiba, MSI, Sony, Samsung, and more.
What Are BIOS Beep Codes?

BIOS beep codes are audio signals produced by the motherboard speaker when:
- The laptop cannot initialize video output
- A critical hardware component fails
- POST cannot complete successfully
Why Beep Codes Are Important
- Useful when screen doesn’t turn ON
- Faster diagnosis than trial-and-error
- Helps avoid unnecessary part replacement

Common Laptop Beep Code Fixing Steps
Step 1: Power Reset
- Remove charger & battery
- Hold power button for 30 seconds
Step 2: Check RAM
- Remove RAM
- Clean contacts
- Test one stick at a time
Step 3: Reset BIOS
- Remove CMOS battery (if accessible)
- Use BIOS reset pinhole (modern laptops)
Step 4: External Display Test
- Connect HDMI monitor
- If display works → LCD issue
Step 5: BIOS Update
- Only if system powers on partially
When Beep Codes Cannot Be Fixed at Home
Seek service if:
- CPU or motherboard failure
- BIOS chip damage
- Power IC failure
- Liquid damage detected
